Abstract (en)
[origin: WO2019201890A1] The invention relates to a thermally active actuator (1) comprising an actuator element (10) made of a metal shape-memory alloy such that the actuator element (10) changes shapes in the event of a temperature change. At least one restoring means (11) made of elastomer is provided, said restoring means being used to restore the shape, and the restoring means (11) is connected to the actuator element (10) via a surface contact. According to the invention, the restoring means (11) is designed as a surface coating of the actuator element (10) and has a layer thickness (d) of 5 μm to 800 μm. The invention additionally relates to a method for producing a thermally active actuator (1).
